Stability testing (according to ICH Q1A) in the pharmaceutical industry, long-term storage, growing plants, conditioning and climate testing of plastic material/metal/composite material, storage of electronic components/lacquers/ coatings in controlled environment.   
   
They are simply unbeatable in energy efficiency. Furthermore, as constant climate chambers HPP have a very long, maintenance free service life, they are perfectly suited for stability tests, storage in controlled environment and conditioning. The high precision temperature control from 0 °C to +70 °C as well as active humidification and dehumidification from 10 % to 90 % rh were particularly adapted to the ICH guidelines, option Q1A, for stability tests.
